Check the owner manual first and match each circuit slot with its labeled amperage before removing anything, as incorrect replacement may damage wiring or onboard electronics.
The main power distribution unit in this minivan is split into multiple sections, including a cabin-mounted panel near the driver side and an under-hood block next to the battery. Each section controls specific systems such as lighting, climate control, infotainment, and safety modules.
Inside the cabin, access is typically gained by removing a plastic cover near the lower dashboard. Printed charts on the cover or manual pages list slot numbers and circuit roles, allowing quick identification of components linked to non-working features.
Under the hood, the electrical center contains higher-amperage elements responsible for engine management, cooling fans, and charging circuits. Always disconnect the battery before working with this area to reduce the risk of short circuits or accidental contact.

Locate the interior panel on the driver side lower dash and match each slot number with the printed layout on the cover to identify circuits tied to lighting, audio, and accessory systems.
The under-hood power distribution unit sits near the battery and contains high-current links for engine control, radiator fans, and charging components, with clearly marked amperage values such as 40A, 60A, and 80A.
Each slot inside the cabin panel corresponds to a specific function, including power windows, central locking, dashboard illumination, and infotainment; use the numbering grid to trace faults quickly.
Rear section panels, if equipped, handle additional circuits for climate control in passenger rows and rear power outlets, with access typically behind a side trim panel.
Amperage ratings are color-coded, allowing quick visual checks: for example, red indicates 10A, blue 15A, and yellow 20A, helping prevent incorrect replacements.
Always verify both the slot number and current rating against the panel legend before replacing any component to avoid damage to connected modules or wiring harnesses.
Exact locations of fuse boxes in cabin engine bay and rear section
Open the driver side lower dashboard cover to access the interior electrical panel, positioned just above the footwell and slightly to the left of the steering column.
This cabin-mounted unit is secured behind a removable plastic trim; pull the edge gently to release clips and reveal the slot grid with numbered positions.
Engine bay location
Lift the hood and locate the main power distribution center near the battery on the driver side, enclosed in a black plastic housing with a snap-on lid.
Release the side tabs to open the cover, where high-current relays and large cartridge-style fuses are arranged in a clearly marked layout for engine and cooling systems.
Rear section access
Check the rear passenger side area behind an interior trim panel or cargo compartment cover, where additional circuits for climate control and auxiliary outlets are installed in a compact block.
